Ok, so I'm looking for some input. I'm really new to vaping and am still going back and forth this week between vaping and smoking while trying to find the right "replacement". Anyway, I bought some cartridges from Vapure as well as some empty cartridges from them, along with a couple bottles of juice. So, I get it in the mail today and decide to try filling one of the empties. So, I follow the instructions, so far, so good and I'm all proud of myself because it goes well and I can blow through the cartridge so there's no extra juice in the line. Nothing is leaking,etc. Put that one down to rest for awhile. I then pull out a cartridge (also from Vapure) that I had used yesterday and couldn't seem to get any more vapor out of so I assumed it was done. I saved it because I want to try to refill the carts a couple of times before throwing them away. So, I do the same exact thing but all the liquid is just going right through it this time. Does that mean the cartridge really wasn't done, and it couldn't absorb all the liquid? I did the instructions the same exact way the second time so I can't figure out what I did wrong.
